Abstract
The invention discloses a volumetric quantitative jet valve which aims to solve the technical problems of accurately controlling the jet volume of packaging materials and enabling the jet volume to be adjustable. The volumetric quantitative jet valve of the invention is provided with a jet cavity with an outlet and a striker arranged in the jet cavity, wherein the striker moves to the outlet of the jet cavity when being driven by the power and restores to the original position under the action of the restoring force; the jet cavity is closed and is connected with a hole pipe with a valve; the hole pipe is connected with a charging barrel; and when the striker is driven by the power and moves, the valve is in a closed state. Compared with the prior art, the invention has the characteristics that the valve is arranged between a closed inner cavity in the shape of an inverted cone and a glue inlet hole pipe, so that when the striker downward strikes the glue in the inner cavity of a nozzle, the glue is jetted from the outlet and can not flow back to the glue inlet hole pipe, and the same valve body can be matched with strikers of different diameters to be suitable for different jet volume. The invention is suitable for adhesives, packaging materials, welding glue, paint and lubricating oil for jetting and filling glue and welding components in the electronic industry process.
Description
Technical field
The present invention relates to a kind of electronics industry special equipment, particularly a kind of injection apparatus for spray filling adhesive that glue, welding component uses, encapsulating material, weldering glue, coating, lubricating oil.
Technical background
The electronic devices and components size that the hyundai electronics industrial products adopt is more and more less, more accurate, mounting means is variation also, therefore need to encapsulating material be sent to assigned address with split-hair mode, do not interfere again other components and parts, and for different environments for use, encapsulating material there is different physical and chemical performance requirements, such as mobile, viscosity, even the performance of partially mixed glue and flow regime temporal evolution and change.Existing technology is with injection valve encapsulating material to be ejected into assigned address.At first encapsulating material is put into barrel, above barrel, by compressed air encapsulating material is extruded from the barrel outlet at bottom, deliver to the spray chamber in the injection valve, by under the striker high-speed impact on the cylinder piston, encapsulating material is ejected from little small-bore exit again.Because the outlet aperture enters the import bore of spray chamber much smaller than glue, encapsulating material is subject to the interior pressure that the striker high-speed extrusion produces, and the encapsulating material major part is flow backwards away from import department, causes the glue amount that ejects to be difficult to control.Viscosity is larger, and the glue amount is more inaccurate.Therefore, existing technology is difficult to satisfy the higher encapsulating material point glue of viscosity, the technology requirement that does not reach electronic product machining.
Summary of the invention
The purpose of this invention is to provide a kind of volume type quantitative injection valve, the technical problem that solve is accurately to control the emitted dose of encapsulating material, opens the emitted dose size adjustable.
The present invention is by the following technical solutions: a kind of volume type quantitative injection valve, spray chamber with band outlet, be arranged on the striker in the spray chamber, striker moves to the outlet of spray chamber when power drive, return back to original position under the restoring force effect, and described spray chamber is closed, its be connected with the hole of valve pipe, the hole pipe connects barrel, and described striker is between power-actuated moving period, and valve is in closed condition.
Volume type quantitative injection valve of the present invention is provided with the fluid control box, and spray chamber, valve, hole pipe and barrel are arranged on the fluid control box.
Spray chamber of the present invention is back taper, and the end outlet is cylindrical hole.
Valve of the present invention adopts aciculiform cylinder CJPB6-5 type, and the hole pipe is formed hermetically-sealed construction.
The power of driving of the present invention is compressed air.
Striker of the present invention connects as one with the piston that is arranged in the cylinder.
Restoring force of the present invention adopts Compress Spring to produce.
Compress Spring of the present invention is nested with on striker, the bottom of an end in contact piston, other end contact cylinder step plane place.
Cylinder upper of the present invention is provided with the stroke adjustment screw rod, and the stroke adjustment screw rod is threaded with cylinder.
Cylinder of the present invention is arranged on the fluid control box, is provided with the first guide pin bushing in the cylinder, and the seal receptacle that arranges in the fluid control box is on spray chamber top, and the first guide pin bushing and seal receptacle axis coaxle arrange.
The present invention compared with prior art, between the back taper inner chamber that seals and glue feeding opening pipe, a valve is set, cut off defeated glue loop, clash into the glue of nozzle inner chamber downwards when striker, it can only be ejected from outlet, can not be back to the glue feeding opening pipe that is connected with barrel, like this, can guarantee to spray glue quantity at every turn and change≤1%, realize each accurate control of spraying glue quantity, directly connecting together of the cylinder block of valve body and magnetic valve, shortened widely gas circuit, the action and the magnetic valve action that guarantee steam-cylinder piston are synchronous, improve significantly the response speed of glue spraying valve, improved the some glue frequency of injection valve: simultaneously, because gas circuit is short, reduced widely the striker movement position deviation that produced by the compressed air compressibility, this also is to guarantee the accurate important measures of glue spraying amount, adopt the spring reset piston, compact conformation, control the impulsive force size of striker by regulating compressed air pressure, to adapt to the viscosity of different encapsulating materials, the scope of suitable material is larger, the injection valve nozzle does not contact precision machined product, is easy to operation and maintenance, in addition, volume type quantitative injection valve of the present invention is designed to the striker of same valve body adapted different-diameter, applicable different emitted dose.
